The representation features a detailed six minute animated lesson about the major processes that move water between land, the ocean and the atmosphere, and convert water between states. A short section, (5:25-5:40 beginning with image of porous soil to narration “along the way”), focuses on the seeping of surface water through soil and cracks in rock.

The resource addresses the actual substance of the learning goal rather than
just the topic.
The resource's narration explains that water seeps down through soil and cracks in rock and eventually flows into streams, lakes and oceans.
The resource addresses the indicated part of the learning goal:
[The water falling on land collects] in rivers and lakes, [soil, and porous layers of rock, and much of it flows back into the oceans.]
The resource correctly reflects the level of sophistication of the learning
The video uses vocabulary and images that reflect the level of sophistication appropriate for middle school.
Notes for Teachers
Quality of instructional support
Does the representation accurately represent relevant aspects of the learning goal and/or brings out limitations that are not accurate?
Yes—The representation accurately represents relevant aspects of the learning goal and brings out inaccuracies, if there are any.
The representation's narration is accurate in its depiction of groundwater seeping through soil and rock, eventually reaching lakes, streams and the ocean.
Is the representation likely to be comprehensible to students?
Partial—The representation might make the learning goal comprehensible to students.
While the narration is accurate, the visual component relies only on a series of photographs of soil, a cave and a rivulet of water flowing through a crack in the rock. Additional information is needed to show the movement of water through the tiny pores in soil or cracks in rocks.
Does the representation make clear which aspects of the real thing are represented and which are not?
Partial—The representation usually, but not always, makes clear which aspects of the real thing are represented and which are not.
It is not clearly stated in this resource what aspects of this representation are real.
Useful with modification
Notes to teachers
Discuss with students ways surface water moves as it seeps into tiny pores in soil and cracks in rocks. Ask students to create their own diagram.
